A shooter is a blanket genre of video game where the player controls a character that can shoot projectiles. Because this definition is so broad, the genre is typically divided into several sub-genres like:
|First-person shooter||The game is seen through the eyes of the character who shoots at opponents.||Doom, Half-Life|
|Fixed shooter||The character is confined to a limited area, usually on a single screen.||Space Invaders, Centipede|
|Platform shooter||The character runs along platforms while shooting.||Ghosts 'N Goblins, Contra|
|Rail shooter||The player shoots at targets while moving along a pre-set course.||Star Wars (1983), Space Harrier|
|Scrolling shooter||The character moves across a large area as the background scrolls behind them.||Defender, Xevious|
Although light gun video games involve shooting, they don't fall into this definition of a shooter because the player's character doesn't fire a projectile. Instead, it uses something called a hitscan.
